휴대전화 소액결제 시스템은 자동결제 처리 시 이용자의 점유인증을 관리하지 않는다. 콘텐츠제공사업자가 이점을 악용하면 허위 결제정보를 생성하여 이용자에게 부당한 요금을 부과할 수 있다. 이와 같은 휴대전화 소액결제 시스템의 구조적 취약점은 소액결제 이용자의 피해로 이어졌다. 이를 해결하기 위해 2012. 8. 이후 이용자의 결제 인증 강화를 위한 표준결제창이 적용되었다. 그러나 표준결제창도 부당한 이용자 피해가 발생할 수 있는 취약점이 존재하는 바 이용자 보호를 위한 개선방안을 제안하고자 한다.

This study aimed to develop a sensory feedback system which could measure force and temperature for the user of myoelectric prosthetic hands. The Sensory measurement module consisted of a force sensing resistor to measure forces and non-contact infrared temperature sensor. These sensors were attached on the fingertips of the myoelectric prosthetic hand. The module was validated by using standard weights corresponding to external force and a Peltier module. Sensory transmission module consisted of four vibration motors. Eight vibration patterns were generated by combining motion of each vibration motor and were dependent on kinds and/or magnitude. The module was verified by using standard weigts and water at varying temperatures. There were correlations of force and temperature between the sensory measurement module and standard weight and water. Additionally, exact vibration patterns were generated, indicating the efficacy of the sensory feedback system for the myoelectric prosthetic hand.

In this paper, we studied on the effective structure of an e-Learning Korean Support System for foreigner based on computer systems which is to obey the rules of IMS/AICC International Standard regulations based on LCMS and SCORM. The most important task on this study is to support the function of self-study module through the review of the analysis and results of Korean learning and learning customs. We studied the effective PMS detail modules as well as the Standard Competency Module Management System, which related to LMS/LCMS, Learning an Individual Competency Management System, Competency Registry/Repository System, Knowledge Management System based on Community Competency Module, Education e-survey System and Module learning Support Service System. We suggested one of standard Effective Model of learning Korean Support System which is adopted in a various techniques for foreigner.

This study deals with 8-cheok(ch"), equivalent to 2.4m as the standard scale of architectural module in Korea. 8ch" of Korean module was a unique dimensions compared to other East-Asian architecture. It is inferred that it spread in Joseon Dynasty by the effects of the law which limited the size of buildings and materials according to social rank. 8ch" module was applied to the Palace architecture and the highest grade mansions rather than common and small houses. The application of 8ch" module changed the process of architectural planning, and bred the essential characteristics of Korean architecture in terms of appearance and techniques. In addition, it developed to gain multiformity of composition by combination of other modules.

In this paper, a standard robot design methodology is suggested and a software architecture for modular robot is introduced. The robot is modularized by several functions, and the module is produced according to a standard proposal. Each module requires standard interface for communicate in distributed environments. Software architecture was developed to support distributed component environment, and application development support tools are developed for user convenience. Many robot softwares are developed in a library form so that, they are being used widely robot application software development. Also a device driver was developed for the mostly used sensor and actuator. It is verified that the modular robot can be applied in various fields through guide, errand and guard scenario.

Let $\mathcal{X}$ be a countably generated Hilbert module over a locally $C^*$-algebra $\mathcal{A}$ in multiplier module M($\mathcal{X}$) of $\mathcal{X}$. We propose the necessary and sufficient condition such that a sequence $\{h_n:n{{\in}}\mathbb{N}\}$ in M($\mathcal{X}$) is a standard frame of multipliers in $\mathcal{X}$. We also show that if T in $b(L_{\mathcal{A}}(\mathcal{X}))$, the space of bounded maps in set of all adjointable maps on $\mathcal{X}$, is surjective and $\{h_n:n{{\in}}\mathbb{N}\}$ is a standard frame of multipliers in $\mathcal{X}$, then $\{T{\circ}h_n:n{\in}\mathbb{N}}$ is a standard frame of multipliers in $\mathcal{X}$, too.

In this paper, we analyze the Transition of Isc by natural solar spectrum of c-Si and a-Si PV module. Commonly, performance of photovoltaic (PV) module is estimated under the standard test condition (STC). That is, solar irradiance $1kW/m^2$, solar spectrum distribution: AM1 5G, module temperature $25^{\circ}C$ This means it rarely meets actual outdoor conditions. The solar spectrum always changes. So it is rare to fit the standard solar spectrum AM1 5G defined in ASTM G173-03 or IEC 60904-3. Thus spectral response of PV module is different depending on the material. so we estimated the variation of Isc at every minutes by comparing c-Si PV module with a-si PV module for outdoor conditions.

EDI(Electronic Data Interchange) allows the exchange of business information and computer-processable data in a standard, structured format electronically between organizational entities. EDI handles the restructuring of a business document into the standard format so that it can be transmitted from one computer to another. This paper identifies features and technologies of web browsed electronic document exchange system as follows 1) the fundamental technologies that consists of the EDI technologies, the Internet/Web technologies, the security/authentication techniques, and the XML implementation technologies. 2) the functions that consists of the document standards, transfer technology of the document, encryption and authentication 3) the implemented Web-EDI systems that consists of document generation module, encryption and authentication module, transfer module, acknowledgement module, administration module. In this paper, the Web-based EDI system implemented from the researched technologies will be installed on the EDI servers owned by corporate customers and enable the exchange of documents between each installed companies.

VXIbus란 모듈화 기기들의 상호 호환성을 위하여 VMEbus를 기본으로 구성된 업계 표준이다. VXIbus 시스템을 구현하기 위한 디바이스는 크게 register based 디바이스와 message based 디바이스로 나눌 수 있으며, 본 논문에서는 slot0모듈과 A/D변환 모듈로 이루어진 register based VXIbus 서브 시스템을 구성하였다. A/D변환모듈은 디지털 전압계로 사용되었으며, 외부 제어컴퓨터와 slot0모듈간의 통신은 LAN을 이용하였다. 한편 SCPI(Standard Commands for Programmable Instruments)는 계측기 언어의 표준화로서 외부 제어 컴퓨터에서 ASCII 형태로 slot0 모듈로 전송되어지며, 다시 2진 형태의 명령어로 변환되어 A/D변환모듈로 전송되어진다. 실험결과 측정된 전압값이 외부 제어 컴퓨터상에서 그래픽 사용자 인터페이스를 통해 관찰할 수 있도록 시스템을 구성하였다.
